Functionalism

The functional theory of boredom maintains that boredom ought to be defined in terms of its role in our mental and behavioral economy. Although the functional theory has recently received considerable attention, presentations of this theory have not specified with sufficient precision either its commitments or its consequences for the ontology of boredom. This essay offers an in-depth examination of the functional theory. It explains what boredom is according to the functional view; it shows how the functional theory can account (...) for the known characteristics of boredom; and it articulates the theory’s basic commitments, virtues, and limitations. Ultimately, by furthering our understanding of the functional theory of boredom, the essay contributes to a better theoretical grounding of boredom. (shrink)

The aim of this paper is to understand the functional role of mental representations and intentionality in skilled actions from a systems related perspective. Therefore, we will evaluate the function of representation and then discuss the cognitive architecture of skilled actions in more depth. We are going to describe the building blocks and levels of the action system that enable us to control movements such as striking the tennis ball at the right time, or grasping tools in manual action. Based (...) on this theoretical understanding the measurement of mental representations and related research results concerning mental representation in skilled action are presented in an overview. This leads to the question how mental representations develop and change during learning. Finally, to consolidate the functional understanding of mental representation in skilled action and interaction, we provide examples how to use the measurement of mental representation in humans to inform technical systems.

Functionalism as a philosophical position has been recently applied to the case of emotion research. However, a number of objections have been raised against applying such a view to scientific theorizing on emotions. In this article, I argue that functionalism is still a viable strategy for emotion research. To do this, I present functionalism in philosophy of mind and offer a sketch of its application to emotions. I then discuss three recent objections raised against it and respond to each of (...) them. These objections claim that functionalism is intractable because (i) it does not support a scientifically interesting taxonomy of emotions for experimental settings, (ii) it is inherently teleological, and (iii) it cannot be falsified. I argue that these objections either rely on a simplified version of functionalism as a philosophical position or they pose challenges that functionalists can readily address. Lastly, I conclude by drawing some lessons these objections suggest for a tractable functionalist account of emotions. (shrink)

In this paper I look into a problem concerning the characterization of the main conceptual commitments of the ‘post-cognitivist’ theoretical framework. I first consider critically a proposal put forward by Rowlands (2010), which identifies the theoretical nucleus of post-cognitivism with a convergence of the theses of the extended and the embodied mind. The shortcomings I find in this proposal lead me to an indepedent and wider issue concerning the apparent tensions between functionalism and the embodied and enactive approaches.

In recent decades, several theories have claimed to explain the teleological causality of organisms as a function of self-organising and self-producing processes. The most widely cited theories of this sort are variations of autopoiesis, originally introduced by Maturana and Varela. More recent modifications of autopoietic theory have focused on system organisation, closure of constraints and autonomy to account for organism teleology. This article argues that the treatment of teleology in autopoiesis and other organisation theories is inconclusive for three reasons: First, (...) non-living self-organising processes like autocatalysis meet the defining features of autopoiesis without being teleological; second, organisational approaches, whether defined in terms of the closure of constraints, self-determination or autonomy, are unable to specify teleological normativity, that is, the individuation of an ultimate beneficiary; third, all self-organised systems produce local order by maximising the throughput of energy and/or material (obeying the maximum entropy production (MEP) principle) and thereby are specifically organised to undermine their own critical boundary conditions. Despite these inadequacies, an alternative approach called teleodynamics accounts for teleology. This theory shows how multiple self-organising processes can be collectively linked so that they counter each other’s MEP principle tendencies to become codependent. Teleodynamics embraces – not ignoring – the difficulties of self-organisation, but reinstates teleology as a radical phase transition distinguishing systems embodying an orientation towards their own beneficial ends from those that lack normative character.

We suggest a teleological approach to subjective experiencing or phenomenal consciousness. Like living, subjective experiencing is a teleology-constituting mode of being, which is made up of coupled, functional processes. We explicate our notion of a 'teleological mode of being' and distinguish between three different modes: a living (non-sentient) mode of being, a sentient mode of being, and a rational-symbolic (human) mode of being, which correspond to the three levels of soul suggested by Aristotle. These evolved teleological modes of being are (...) characterized by the possession of distinct, hierarchically nested goals and value systems. We argue that the functions of parts and processes within living systems have to be situated within the appropriate teleological frame of reference. Our evolutionary and comparative approach to the mode of being of subjectively experiencing animals clarifies why functions are best attributed to the parts that constitute sentience. Our proposal resolves the problem of attributing functions to phenomenal consciousness, resonates with basic teleological intuitions and distinctions, and corresponds to the modern broad understanding of selection and evolution.

According to pure imperativism, pain experiences are experiences of a specific phenomenal type that are entirely constituted by imperative content. As their primary argument, proponents of imperativism rely on the biological role that pain experiences fulfill, namely, the motivation of actions whose execution ensures the normal functioning of the body. In the paper, I investigate which specific types of action are of relevance for an imperative interpretation and how close their link to pain experiences actually is. I argue that, although (...) imperative theories constitute an apparently promising version of strong intentionalism, they cannot provide an imperative content that meets their own criteria of both sufficiency and necessity. I further argue that this issue cannot be solved by impure imperative theories either. (shrink)

A common kind of explanation in cognitive neuroscience might be called functiontheoretic: with some target cognitive capacity in view, the theorist hypothesizes that the system computes a well-defined function (in the mathematical sense) and explains how computing this function constitutes (in the system’s normal environment) the exercise of the cognitive capacity. Recently, proponents of the so-called ‘new mechanist’ approach in philosophy of science have argued that a model of a cognitive capacity is explanatory only to the extent that it reveals (...) the causal structure of the mechanism underlying the capacity. If they are right, then a cognitive model that resists a transparent mapping to known neural mechanisms fails to be explanatory. I argue that a functiontheoretic characterization of a cognitive capacity can be genuinely explanatory even absent an account of how the capacity is realized in neural hardware. (shrink)

Author’s Preface in English: My Two Discoveries and Their Philosophical Significance As long as a person opens his eyes to face this world, he will meet the problems discussed in this book. Is the red color of flowers and the green color of grass displayed in front of our eyes only sensations in our minds or objective existence as the same as we see? Is a color perception similar to or different from a natural light that objectively exists? The further (...) question is: Are red flowers and green grass just our sensations in minds or what objectively exists in the way as we see, or what exists differently from our sensations? As early as ancient ages of Greece, atomists gave us a rather scientific answer. It is said that what objectively exists is only the material world made of atomics. The motion of atomics causes human sensations. Color, sound, smell… are all human sensations, and related to human sense organs’ conformations, and different from those atoms that cause sensations (I will explain why the answer is not entirely correct later). The answer from modern natural science is very similar. However, this answer brings a series of philosophical problems that puzzle us. If red and green colors are only sensations in human minds, why red flower and green grass are not? If a sensation is totally different from the external object or its property that causes a sensation, how can we know the appearance of the outside object itself? The problems brought by atomists are just revealed by the philosophically fundamental questions proposed by Engels, i.e., the question about the relationship between thinking and existence, which includes two questions: the question about the original existence of the world and the question about whether the world is knowable. I know there is a fashionable opinion: the fundamental question in philosophy, or the question about the original existence of the world, is a false question, and the argument between materialism and idealism is meaningless because there are no different sensations or experiences deduced from the affirmations about whether the world is made of matter or spirit. But, I still persist in discussing the fundamental questions in philosophy. This is not because I have some faith and fight for the faith, neither because I have encyclopedical knowledge so that I can provide better summing-up. This is only because I happened to have two discoveries, which force me and also force academe，to review the fundamental questions in philosophy from a new visual angle to get conclusions that accord with natural science better. My first discovery is that idealism, positivism，and materialism (mainly native materialism) all wrongly understand the relationship between language, sensations, and outside objects. In daily life, we define words “red”, “green”, “acid”, “salt”, “soft”, “hard”, “cold”, “hot” and son on actually according to outside objects instead of sensations. The conformability of people’s speaking language cannot ensure the conformability of their sensations (for example, it is possible that two persons conformably say “flower is red and the grass is green” and have opposite color perceptions ). It is unfeasible to reduce the world with red, green, acid, salt, cold, hot, and other material properties into sensations as idealism does, into world-elements as Machism does, or into sense-data as logical empiricism does. It is also unfeasible to affirm that a sensation is similar to a material property as inornate materialism does. This discovery forces me to believe that 1) The world described by daily language is not the natural world, phenomenological world, or presentational world proposed by Kant, neither neutral world or a world made of elements or sense data, but the material world that objectively exists as affirmed by materialism. 2) Atomists in ancient Greece and symbolists, such as Kant and Helmholtz of Germany, are correct in affirming the dissimilarity between a sensation and a material property that causes the sensation. Atomism and mechanical materialism represented by John Locke’s theory affirm that the motion of Atoms or matter causes human sensations; yet, a consciousness and a material property are totally dissimilar. However, symbolists represented by Kant and Helmholtz further affirm that the sensations in organs are only symbols, they are discretional, and there is no certain one-to-one relation between a sensation and a material property. This point of view is called agnosticism. So far, my above conclusion is probably also thought of as agnosticism. However, I happened to have a second discovery. My second discovery is that there exists a skillful mathematical model of color vision——the decoding model 【8～10】, whose principle is similar to the principle of 3-8 decoder in numeric circuits. The model can explain various phenomena of color vision, especially the evolution of color vision, better. We can conclude from the decoding model that 1) A color perception is only a symbol that can continuously vary. 2) A series of color perceptions contain information from external objects since different color perceptions reflect different natural lights, even if a color perception is dissimilar to a material property. 3) The mechanism of color vision was continuously evolving for the requirement of discerning outside objects. The presentational or phenomenological world was involving with the mechanism of color vision involving, by which the objectify theory developed by Feuerbach and Marx can be explained in the way of natural science. The generalized information theory I set up is tightly related to my second discovery. For measuring the information conveyed by color vision, I extended Shannon’s information theory to general information theory, which can measure and optimize sensitive information, as well as the information conveyed by language and forecasts. The results from the generalized information theory are consistent not only with common sense but also with Popper’s philosophical theory. For example, according to this theory, the more necessary an occasional event is predicted as, and the prediction can be proved correct by facts, the more information the prediction conveys; a proposition that is true in any case provides no information; a lie or bad prediction conveys negative information; it will decrease the information we have had to believe a fortune teller is running off at the mouth. There are mainly two kinds of agnosticism. One is Kant’s agnosticism, which affirms thing-in-itself (or objective thing) is unknowable. Another is Hume’s agnosticism, which affirms the relationship between a cause and a result (or objective rule) is unknowable. Marx’s practice-testing theory and Popper’s knowledge-evolving theory can resolve the problem with Hume’s agnosticism. But, about whether the problem with Kant’s agnosticism has been resolved, there are still arguments. Kant would have said that what you have resolved is only the problem about whether the phenomenological world is knowable; however, you still cannot resolve the problem about whether the thing-in-itself, which is totally different from sensations, is knowable. Now, with the help of my two discoveries and new information theory, we can have two ways to prove the thing-in-itself is knowable. 1) We know that the objects described by daily language are knowable. Yet, the objects pointed by daily language are just material objects themselves. So, material objects themselves are knowable, or say, the thing-in-itself is knowable. 2) Although sensations are dissimilar to material objects or their properties, they contain information about material objects. This information can be measured by the generalized information formula similar to Shannon’s information formula. So, the material object or the thing-in-itself is knowable from the point of view of natural science. Moreover, my research concerning lingual information also supports Mark’s practice-testing theory and Popper’s knowledge-evolving theory. So, agnosticism does not fit my standpoint at all. For explaining the relationship between sensations and outside objects and summarizing up my research, I proposed analog-symbolic theory or analog-symbolism, which is based on Darwin’s theory of evolution, the theories of color and color vision developed by Young and many later researchers, and also my theories on color vision and information. The analog-symbolism is also the extension of the relativistic principle from physics to philosophy. It accepts atomists and mechanical materialists’ viewpoint about the relation between the sensation and the outside object (the motion of matter results in the sensation, however a sensation and a material property are dissimilar), affirms and extends Kant and Helmholtz’s symbolism, carries on the relativity thought in Feuerbach and Marx’s objectify theory (for resolving the problem with Kant’s dualism), inherits Lenin and many materialists’ viewpoint that color, sound, smell… objectively exist（against idealism and positivism）. This book has both scientific explorations and philosophical analyses. However, what it provides is very different from a popular scientific philosophy. The popular scientific philosophy is supposed to sum up, and guide science. But my effort is the opposite. I always try to base my philosophy on science. For example, I use a mathematical model of color vision to explain that the sensations are analog symbols, use the information theory to resolve the problems with agnosticism, and extend relativity principle from physics to philosophy. I have unified many very extreme standpoints together in my theory. These standpoints look mutually repulsive to other people, yet from my viewpoint, they are not contradictive with each other but very compatible. The primary purpose of this book is to eliminate the people’s bepuzzlement about the fundamental questions in philosophy. Before writing this book, I wrote another book: “Mystery of Beauty-feeling and Evolution of Demand,” whose primary purpose is to eliminate the people’s bepuzzlement about problems with beauty-feeling and demand. It is also based on some discoveries — about the arising rule of pleasant feelings and avian esthetic interest. These two books respectively discuss the cognitive relationship and motivational relationship between humans and outside would. They are comprehensive summing-up of my many years’ researches. If my effort is not ineffectual, I will be incomparably gratified. Lu, Chenguang . (shrink)

This paper shows why qualia constitute a problem for any theory of mental phenomena. We use the term ‘qualia’ in reference to non-intentional features of mental states which are eminently qualitative, i.e. perceptions, emotions, moods and body sensations. These non-intentional features are usually described as intrinsic, ineffable, infallible, atomic, private, direct and irreducible to the physical. The paper also explains the absent qualia argument which is addressed as a critique to functionalism.

This paper explains the main theses of functionalism about mental states. This view is taken as a response addressed to the metaphysical aspect of the mind-body problem. It is explained what distinguishes functional properties as second-order properties, and how to understand supervenience and multiple realizability. The paper applies these ideas to machine functionalism and analytic functionalism, the two main versions of functionalism.

Recent work on quantum gravity suggests that neither spacetime nor spatiotemporally located entites exist at a fundamental level. The loss of both brings with it the threat of empirical incoherence. A theory is empirically incoherent when the truth of that theory undermines the empirical justification for believing it. If neither spacetime nor spatiotemporally located entities exist as a part of a fundamental theory of QG, then such a theory seems to imply that there are no observables and so no way (...) that the theory can be confirmed. The threat of empirical incoherence can be addressed by treating spacetime and spatiotemporally located entities as emergent. The question then arises as to what the metaphysical nature of this emergence might be. In this paper, I explore a functionalist approach to this kind of emergence in the context of loop quantum gravity. I begin by rehearsing the spacetime functionalist’s account of emergence, clarifying the view along the way. I proceed to sketch out a functionalist treatment of spatiotemporally located entities and combine the two forms of functionalism into a double functionalism, according to which both spacetime and matter have the same functional realisers.

In this dissertation, I examine our mental health concepts to see what work they are currently doing as well as what work they could be doing. In 1976, Christopher Boorse stated that the mental health literature is a “web of obscurities” (p. 51). To resolve some of this confusion, I argue that we need to consider the goals we should have for our mental health concepts and then give accounts of those concepts that meet our stated goals. I argue that (...) our goals for our mental health concepts should be twofold: first, we need concepts that will work to alleviate the stigmatization of mental disorder as this stigmatization gets in the way of providing and receiving medical help, and second, we need concepts that will be useful tools for medical practitioners to use in their diagnosis and treatment practices. -/- I begin by arguing that our mental disorder concept is not currently a useful tool for medical practitioners. Moreover, I argue that our mental disorder concept is confused in such a way that it is unlikely that it could ever be a useful tool for medical practitioners. If we cannot give an account of the mental disorder concept that is a useful tool for medical practitioners, then perhaps we can give an account of the mental disorder concept that can be used toward our goal of alleviating the stigmatization of mental disorder. Before we can do that, however, we need an account of the stigmatization concept so that we can understand what our mental disorder concept needs to be alleviating. -/- I argue that stigmatization is a process whereby some entity becomes marked as disgraceful or shameful. This stigmatization process includes (1) an attitude against the entity for reasons found in the social ideology, and (2) acts against the entity. I then argue that acts of stigmatization take two forms: direct stigmatization (where stigmatizors take acts against the stigmatized entity) and indirect stigmatization (where potential victims of stigmatization take acts to avoid becoming victims of stigmatization). With that in mind, we learn that if we are to alleviate the stigmatization of mental disorder, we need to work on alleviating both direct and indirect stigmatization. It is at this point that I argue for a new account of our mental disorder concept that can be utilized to alleviate the direct and indirect stigmatization of mental disorder. With our mental disorder concept redesigned to achieve that goal, I turn to the goal of providing medical help for persons that need that help. I argue that we need to reconceptualize what it means to be a ‘diagnosable condition’ so that we can develop a new framework for diagnosis and treatment that will be more efficacious than our current system. In conclusion, I suggest that we can untangle the current confusion that is the mental health literature by imbuing our mental health concepts with specific purposes and then utilizing them to achieve those purposes as I outline in this dissertation.

I analyze a tension at the core of the mechanistic view of computation generated by its joint commitment to the medium independence of computational vehicles and to computational systems possessing teleological functions to compute. While computation is individuated in medium-independent terms, teleology is sensitive to the constitutive physical properties of vehicles. This tension spells trouble for the mechanistic view, suggesting that there can be no teleological functions to compute. I argue that, once considerations about the relevant function-bestowing factors for computational (...) systems are brought to bear, the tension dissolves: physical systems can have the teleological function to compute.

In this paper, we evaluate the pragmatic turn towards embodied, enactive thinking in cognitive science, in the context of recent empirical research on the memory palace technique. The memory palace is a powerful method for remembering yet it faces two problems. First, cognitive scientists are currently unable to clarify its efficacy. Second, the technique faces significant practical challenges to its users. Virtual reality devices are sometimes presented as a way to solve these practical challenges, but currently fall short of delivering (...) on that promise. We address both issues in this paper. First, we argue that an embodied, enactive approach to memory can better help us understand the effectiveness of the memory palace. Second, we present design recommendations for a virtual memory palace. Our theoretical proposal and design recommendations contribute to solving both problems and provide reasons for preferring an embodied, enactive account over an information-processing treatment of the memory palace.

This paper advances a theory of interactionist mental causation within a non-physicalist property dualist framework. It builds from Chalmers' argument that non-physical experiences can't have causal powers. It reinterprets this as a constraint, then identifies the unique model satisfying it. This has the experience existing passively with physical nature responding actively to it. The paper explores the causal theory presupposed thereby; applies its model to standard property dualism and particulate property dualism ; shows how the model coheres with science; integrates (...) it into a revised functionalist framework having three levels instead of the usual two; explains why consciousness detectors will remain impossible; and argues that dualists should find the model troubling.

The role of a functionalist account of phenomenal properties in Keith Frankish's illusionist position results in two issues for his view. The first concerns the ontological status of illusions of phenomenality. Illusionists are committed to their existence, and these illusions would appear to have phenomenal features. Frankish argues that functionalism about phenomenal properties yields a response, but I contend that it doesn't, and that instead the illusionist's basic account of phenomenal properties must be reapplied to the illusions themselves. The second (...) concern is that phenomenal properties would seem to be intrinsic properties of experience, but functionalism has them consist solely in relations. The nonfunctionalist option can recapture the sense that these properties are intrinsic. It can also preserve the intuition that they are causal powers in a robust sense, and thereby, perhaps surprisingly, provide a stronger response to the knowledge and conceivability arguments.

It has often been thought that compositional variation across systems that are similar from the point of view of the special sciences provides a key point in favor of the multiple realization of special science kinds and in turn the broadly nonreductive consequences often thought to follow from multiple realization. Yet in a series of articles, and culminating in The Multiple Realization Book, Tom Polger and Larry Shapiro argue that an account of multiple realization demanding enough to yield such nonreductive (...) consequences implies that compositional variation is far less significant for the multiple realization of special science kinds than many have supposed. I argue, in contrast, that even on this demanding account, lower-level compositional variation may frequently support the multiple realization of special science kinds across the systems of interest, and that there is a good explanation for where Polger and Shapiro go wrong in drawing the contrary conclusion. I consider but reject Carl Gillett’s claim that different views about the significance of compositional variation for multiple realization phenomena should be traced to implicit disagreement about the metaphysics of realization.

In discussing the famous case of Otto, a patient with Alzheimer’s disease who carries around a notebook to keep important information, Clark and Chalmers argue that some of Otto’s beliefs are physically realized in the notebook. In other words, some of Otto’s beliefs are extended into the environment. Their main argument is a functionalist one. Some of Otto’s beliefs are physically realized in the notebook because, first, some of the beliefs of Inga, a healthy person who remembers important information in (...) her head, are physically realized in her internal memory storage, and, second, there is no relevant functional difference between the role of the notebook for Otto and the role of the internal memory storage for Inga. The paper presents a new objection to this argument. I call it “the systems reply” to the functionalist argument since it is structurally analogous to the “the systems reply” to Searle’s Chinese room argument. According to the systems reply to the functionalist argument, what actually follows from their argument is not that beliefs of Otto are physically realized in the notebook but rather that the beliefs of the hybrid system consisting of Otto and his notebook are physically realized in the notebook. This paper also discusses Sprevak’s claim that the functionalist argument entails radical versions of extended mental states and shows that his argument is also vulnerable to the systems reply.

The debate concerning the reality of qualia has stagnated. The dominant functionalist approach to qualia concentrates largely on the filter-strategy as applied to color experiences. The filter-strategy takes color experiences as material-to-be-functionally-filtered under the assumption that qualia as such cannot be filtered. However, despite the speculative efforts made in this direction, the debate between phenomenalists and representationalists remains unresolved. The main idea of this paper is to show that the lack of success settling “the qualia war” has to be understood (...) as a result of the mischaracterization of colors as a material-to-be-functionally-filtered.

Defending or attacking either functionalism or computationalism requires clarity on what they amount to and what evidence counts for or against them. My goalhere is not to evaluatc their plausibility. My goal is to formulate them and their relationship clearly enough that we can determine which type of evidence is relevant to them. I aim to dispel some sources of confusion that surround functionalism and computationalism. recruit recent philosophical work on mechanisms and computation to shed light on them, and clarify (...) how functionalism and computationalism mayor may not legitimately come together.

In this paper I provide a compelling argument against the thesis that Aristotle’s understanding of the relation between the soul and the body can be construed asfunctionalist, despite some passages that would seem to support such an interpretation. Toward this end, in section I of the essay I offer an interpretation of Aristotle’s account of the soul-body relation that emphasizes the non-contingent nature of the connection between the soul and a specific kind of body, arguing that Aristotle’s account of the (...) soul as the “form” and “actuality” of the living thing, and of the organic body as its “matter” and “potentiality,” shows their necessary relation with one another. In section II, I present the functionalist account of mind, placing especial emphasis on its post-Cartesian genesis, which takes seriously the “problematic” status of the relation between mind and body. I then attempt to show, in section III, how because functionalism holds that psychic capacities can be realized within a number of different material bases, including physical and artificial systems, it is incompatible with Aristotle’s conception of the necessary soul-body relation, and thus that Aristotle’s account of psuche is not best construed as functionalist.

In this article I explore a number of questions that have not been adequately investigated in philosophy of mind circles: are minds located in the same place as the brains (or other computing machinery) supporting them? Must they exist at the same location as the body? Must they exist at the same time? Could a single mind be implemented in multiple brains, or multiple minds in a single brain? Under what conditions might a single mind persist despite being implemented successively (...) in different brains? What contributions do features of the computing machinery make to these questions, compared to the contribution made by the body and embedded point of view? Some of these questions have been touched on previously, but there hasn’t been any attempt at a systematic analysis of the various consequences that different approaches in the philosophy of mind have for how the spatiotemporal location, synchronic individuation and diachronic identity of minds relates to the spatiotemporal location, synchronic individuation, and diachronic identity of both the implementing computational machinery and the embodied embedded point of view. I make a first stab at such an analysis by discussing a variety of thought experiments in which such questions of location, individuation, and identity arise, and I explore how various approaches to understanding the mind – identity theoretic, functionalist, contentualist, embodied/embedded/extended, and so forth – would respond to such situations. A number of novel issues emerge, and some surprising affinities are revealed. (shrink)

Delusions belong to the same category as beliefs but - unlike healthy irrational beliefs - fail to play the function of beliefs. Delusions and Beliefs: A Philosophical Inquiry (...) will be of great interest to students of philosophy of mind and psychology and philosophy of mental disorder, as well as those in related fields such as mental health and psychiatry.

It is well known that humans represent the mental states of others and use these representations to successfully predict, understand, and manipulate their behaviour. This is an impressive ability. Many comparative psychologists believe that some non-human apes and monkeys attribute mental states to others. But is this ability unique to mammals? In this paper, I review findings from a range of behavioural studies on corvids, including food caching, food recaching and food sharing studies. In order to protect their caches from (...) being pilfered, corvids successfully keep track of observing conspecifics, employ a number of caching and recaching strategies, and exploit environmental factors to reduce the amount of visual and auditory information available to observing conspecifics. When giving food items as gifts, corvids give items for which conspecifics have developed a preference. I argue that the available evidence supports the hypothesis that corvids attribute mental states to conspecifics. I further hypothesize that corvids do so through process-driven simulation and the running of non-verbal multimodal rules accomplished by a class of mental representations called semantic pointers.

In this article I argue that two received accounts of belief and assertion cannot both be correct, because they entail mutually contradictory claims about Moore's Paradox. The two accounts in question are, first, the Action Theory of Belief, the functionalist view that belief must be manifested in dispositions to act, and second, the Belief Account of Assertion, the Gricean view that an asserter must present himself as believing what he asserts. It is generally accepted also that Moorean assertions are absurd, (...) and that BAA explains why they are. I shall argue that ATB implies that some Moorean assertions are, in some fairly ordinary contexts, well justified. Thus BAA and ATB are mutually inconsistent. In the concluding section I explore three possible ways of responding to the dilemma, and what implications they have for the nature of the constitutive relationships linking belief, assent and behavioural dispositions.

In Natural Minds Thomas Polger advocates, and defends, the philosophical theory that mind equals brain -- that sensations are brain processes -- and in doing so brings the mind-brain identity theory back into the philosophical debate about consciousness. The version of identity theory that Polger advocates holds that conscious processes, events, states, or properties are type- identical to biological processes, events, states, or properties -- a "tough-minded" account that maintains that minds are necessarily indentical to brains, a position held by (...) few current identity theorists. Polger's approach to what William James called the "great blooming buzzing confusion" of consciousness begins with the idea that we need to know more about brains in order to understand consciousness fully, but recognizes that biology alone cannot provide the entire explanation. Natural Minds takes on issues from philosophy of mind, philosophy of science, and metaphysics, moving freely among them in its discussion.Polger begins by answering two major objections to identity theory -- Hilary Putnam's argument from multiple realizability and Saul Kripke's modal argument against mind-brain identity. He then offers a detailed account of functionalism and functional realization, which offer the most serious obstacle to consideration of identity theory. Polger argues that identity theory can itself satisfy the kind of explanatory demands that are often believed to favor functionalism. (shrink)

Most ethical work is done at a low level of formality. This makes practical moral questions inaccessible to formal and natural sciences and can lead to misunderstandings in ethical discussion.

The main claim of this paper is that Andy Clark's most influential argument for ‘the extended mind thesis’ (EM henceforth) fails. Clark's argument for EM assumes that a certain form of common-sense functionalism is true. I argue, contra Clark, that the assumed brand of common-sense functionalism does not imply EM. Clark's argument also relies on an unspoken, undefended and optional assumption about the nature of mental kinds—an assumption denied by the very common-sense functionalists on whom Clark's argument draws. I also (...) critique Mark Sprevak's reductio of Clark's argument. Sprevak contends that Clark's argument does not merely entail EM; it entails an extended mind thesis so strong as to be absurd. He goes on to claim that Clark's argument should properly be viewed as a reductio of the very common-sense functionalism on which it depends. Sprevak's argument shares the flaw that afflicts Clark's argument, or so I claim. (shrink)

What are the prospects for a monistic view of biological individuality given the multiple epistemic roles the concept must satisfy? In this paper, I examine the epistemic adequacy of two recent accounts based on the capacity to undergo natural selection. One is from Ellen Clarke, and the other is by Peter Godfrey-Smith. Clarke’s position reflects a strong monism, in that she aims to characterize individuality in purely functional terms and refrains from privileging any specific material properties as important in their (...) own right. I argue that Clarke’s functionalism impairs the epistemic adequacy of her account compared to a middle-ground position taken by Godfrey-Smith. In comparing Clarke and Godfrey-Smith’s account, two pathways emerge to pluralism about biological individuality. The first develops from the contrast between functionalist and materialist approaches, and the second from an underlying temporal structure involved in using evolutionary processes to define individuality.

The Mind-Brain Identity Theory lived a short life as a respectable philosophical position in the late 1950s, until Hilary Putnam developed his famous argument on the multiple realizability of mental states. The argument was, and still is, taken as the definitive demonstration of the falsity of Identity Theory and the foundation on which contemporary functionalist computational cognitive science was to be grounded. In this paper, in the wake of some contemporary philosophers, we reopen the case for Identity Theory and offer (...) a solution to the problem of multiple realizabilty. The solution is based on the necessity, at the time of establishing identity relations, of appealing to the notions of “homology” and “analogy” developed in the nineteenth century by Richard Owen. We also suggest that these notions are useful in order to correct certain shortcomings of some recent attempts at rebutting the Multiple Realizability argument. (shrink)

In his seminal work, Representation and Reality and elsewhere in publications throughout the 1980's and 1990's, Hilary Putnam attempts an ingenious refutation of computational functionalism. His refutation centers upon three main pillars: the use of the Godel incompleteness theorems, his precise articulation of a triviality thesis and his argument that there can be no local computational reductions . ;We argue that each pillar is riddled with severe problems. His rescue of the Godel incompleteness theorems from the logical error committed by (...) J. R. Lucas and Roger Penrose comes only at the expense of his argument succumbing to a paradox. His triviality theorem commits a modal error and faces a Kripke-Wittgenstein problem. We also show that both John Searle's metaphysics of computation and current triviality arguments fail to respect theorems of computability and computational complexity theory. We demonstrate, by a relative consistency proof, that computational ism is not committed to metaphysical realism and escapes Quinean indeterminacy and ontological relativity. The demonstration is relative to the success of Putnamian epistemic semantics. We argue that Putnam's no-local-computational-reduction claim amounts to nothing more than a claim that inductive reasoning cannot be formalized, that it erroneously saddles computationalism with radical Quinean meaning holism and that he fails to take into account well-known work in mathematical logic, cognitive science and artificial intelligence.

My dissertation is an attempt to reconcile two plausible and widely held claims: first, that reasons explain actions, and second, that actions have sufficient physical causes. These claims come into conflict when we make the following three common assumptions: one, that beliefs, desires and other intentional states are irreducible to physical states; two, that a physical causal explanation of a particular event will make redundant a mental causal explanation of that same event; and three, that reason-giving explanations are causal explanations. (...) I bring the initial two claims back into compatibility by defending the first two assumptions and rejecting the third. In maintaining that reason-giving explanations are not causal explanations per se, and thus not in competition with physical causal explanations, I show how it is possible for reasons to genuinely explain actions despite the fact that actions have sufficient physical causes. ;I explore in some detail the main reasons why the causal approach to reason-giving explanations is problematic. One focus is the "Exclusion Argument," which purports to demonstrate the causal irrelevance of intentional states to physical events. But explaining how beliefs and desires can be causally efficacious assuming nonreductive physicalism is only part of the problem. I argue that alternative accounts of causal relevance may vindicate the causal efficacy of intentional states, but there is still the question of how these causal claims and explanations relate to physical causal claims and explanations for the same event. I consider two possible solutions to this causal and explanatory competition, and argue that neither is successful. ;My alternative account is a novel brand of functionalism about intentional properties. Intentional properties are second-order properties that have their explanatory power by specifying functional roles that are ultimately filled by physical states. The roles form part of a system that we use to describe and understand our own and others' behavior. Second-order properties are not causally relevant, but they do have explanatory relevance. Reason-giving explanations do not compete with physical explanations because they are not themselves causal explanations, nor are they independent from physical causal explanations. (shrink)

Functionalism represents the most promising as well as the most severely criticized approach to the philosophy of mind. In this dissertation functionalism is defended as a theory of the propositional content of intentional states. The first chapter is a criticism of the competing theories of propositional content: anti-mentalism, instrumentalism, and nonfunctionalist materialism. Theories of the first two kinds are open to straightforward counterexamples. Theories of the third sort are open to counterexamples on the assumption that the distinction between physical and (...) functional properties is neither incoherent nor arbitrary. It is shown that the criticisms which have been advanced against this assumption do not succeed. ;The second chapter is an account of the notion of a partial state functional description and its place in a theory of content. The role of radical interpretation in a theory of content is discussed and a method of assigning content to the partial functional state is elaborated. ;The third chapter is a treatment of the distinction between occurrent and dispositional mental states. The distinction which is relevant to philosophy of mind is between states which are causally efficacious and those which are not. It is argued that the occurrent/dispositional distinction so construed is definable in terms of partial state functional descriptions and a definition is provided. ;The fourth chapter is an account of the instantiation relation between physical systems and abstract automata. Conventionalism with respect to instantiation is the thesis that any causal system which is sufficiently large will instantiate any functional description. Counterexamples are provided to the most extreme version of the conventionalist thesis. General arguments are provided that the strategies which a conventionalist might employ in defending a weaker version of the thesis will not succeed. The chapter concludes with a formulation of the instantiation relation. ;The fifth chapter reconciles functionalism as a kind of autonomous psychology with causal theories of the referential content of intentional states. It is argued that although functional states do not determine propositions, they determine a kind of semantic content which is relevant to psychological explanation. (shrink)

In this dissertation I challenge the functionalist theory of mental states, which asserts that mental types such as "pain" are "multiply realizable" causal relations. ;I begin by providing historical and theoretical background which is necessary for one to fully appreciate functionalism. I show why formerly fashionable theories of mind have fallen out of favor, review Davidson's arguments that reasons are causes, and give a brief account of "folk psychology." ;In discussing functionalism proper, I distinguish between two forms of the thesis: (...) Folk functionalism holds that, e.g., the concept "pain" is the concept of something occupying a causal role. Psychofunctionalism claims that pain is a causal state, whether or not the word "pain" means this. ;Both versions are false. In criticizing folk functionalism I argue that many mind concepts are not concepts of states occupying a causal role. I also argue that the type-token distinction is deeply flawed. Finally, as a theory of mental types, functionalism is committed to the mistaken proposition that all mental particulars of a certain type such as pain have something in common. ;Psychofunctionalism is likewise false. What psychofunctionalists offer as examples of causal roles type identifying mental states are not in fact multiply realizable, and a functionalist theory of multiply realizable mental states would be hopelessly vague. Second, psychofunctionalism masquerades as a scientific hypothesis when in fact it is unable to advance a scientific claim, being neither verifiable nor falsifiable by scientific means. Finally, I show that, though the highly-acclaimed inverted spectrum and absent qualia arguments fail to defeat functionalism, there exists a qualia objection which does defeat it. (shrink)
